[SOLVED] File chooser selecting file from directory...?

[prabhurangan]

Hi All,

While selected a file from FileChooser, file name along with its extension is retrieved, but for me i need only the filename;
For example:
if my file name is 'name.log' and if i select the file name from the directory, i should get only the file name 'name' alone instead, im getting the file name with its extension as 'name.log' and if i save it, it consider it as a new file name and saves it as 'name.log.log' as a new file and file already exist error is not thrown.

Looking forward for reply.

Prabhu.

Find the index of '.' and get the name, as a substring of the file name.

Hi Eranga,

Im java.io.File to get the file name from JfileChooser;
File fileName = chooser.getSelectedFile();

and how to do substring with this, if it is a string type then we can do substring.

Looking forward for your reply.

First of all getSelecteFile() gives the full file path.

[prabhurangan]

Yes you are right eranga, but this gives the file path with the extension of the file also; if i select the file name that is already exist; example 'test' is my file name and its extension is '.txt' and if i select the file 'test', from the save dialog file directory, it retrieves the file name with its extension, 'test.txt' and treats it as a new file and if i click save it is not throwing any error, it saves as 'test.txt.txt'.

Eranga i hope you could get me, of what im trying to explain you.

Looking forward for your reply.

Prabhu.

Ya, I get you. fileName is an object reference of File right? So what you can do?

Code:

                File fileName = chooser.getSelectedFile();
                String temp = fileName.toString();
                String name = temp.substring(temp.lastIndexOf("\\") + 1, temp.lastIndexOf("."));
                System.out.println(name);

Thank you Eranga; this is what i need, but can you please go through my last post, again im facing that issue.

Quote:

JFileChooser chooser = new JFileChooser();
chooser.setCurrentDirectory( new File( "./") );
int actionDialog = chooser.showSaveDialog(this);
if ( actionDialog == JFileChooser.APPROVE_OPTION )
{
//File fileName = new File( chooser.getSelectedFile( ) + ".log" );
File fileName = chooser.getSelectedFile();
String temp = fileName.toString();
String name = temp.substring(temp.lastIndexOf("\\") + 1, temp.lastIndexOf("."));
//File file_name = new File(name);
//System.out.println(name);
if(fileName.exists())
{
int confirmDialog = JOptionPane.showConfirmDialog(this, "Replace existing file?");
if (confirmDialog == JOptionPane.NO_OPTION)
{
chooser.showSaveDialog(this);

}
if(actionDialog == JOptionPane.YES_OPTION)
{
BufferedWriter outFile = new BufferedWriter( new FileWriter( name ) );
outFile.write( getTxtArea_log().getText( ) ); //put in textfile
outFile.flush( ); // redundant, done by close()
outFile.close( );
}

//AttestDialog.getInstance( ).showErrorDialog(languageBundle.getString("LogFil eAlreadyExists"));
}

How to use this modified file name in our dialog, when a file name is selected.

You mean still you have that validating the existing file?

[prabhurangan]

Yes Eranga,
I need my save as dialog to perform, as it is in a wordpad document. I think im saying again and again the same grinded flour. Can you please check a word document and try to save it with existing file name. The same logic i need it in java swing, while saving a file.

Regards,
Prabhu.

[Eranga]

Check the simple logic, just written this and you have to change according to your application.

Code:

    private void workignWithChooser() {
        try {
            JFileChooser chooser = new JFileChooser(new File("./"));
            boolean isValid = true;
            
            do{
                int chooserStat = chooser.showSaveDialog(this);

                if(chooserStat == JFileChooser.APPROVE_OPTION) {
                    // Do the process
                    File userFile = chooser.getSelectedFile();
                    if(userFile.exists()) {
                        System.out.println("File exist");
                        int result = JOptionPane.showConfirmDialog(this, 
                                "Replace existing file?");
                        if(result == JOptionPane.YES_OPTION) {
                            // Save and exit
                            isValid = false;
                        }
                        else if(result == JOptionPane.NO_OPTION) {
                            //any logic if you have
                        }
                    }
                    else {
                        System.out.println("file is not exsit");
                    }
                }
                else if(chooserStat == JFileChooser.CANCEL_OPTION) {
                    System.exit(0);
                }
            }while(isValid);
            System.exit(0);
        }
        catch(Exception e) {
            System.out.println(e.getLocalizedMessage());
        }
    }

Prabhu.

[prabhurangan]

Thank you very much Eranga. I got my solution, after making some modifications to your code. I will get back to you on further post.

Bye take care.
